Product Descriptions :
4-Point Bending Tester measures the bending stiffness of corrugated board and heavy paperboard rapidly and accurately. The unique design of the pneumatic clamps permits measurements of warped and twisted samples without impairing results.
- This tester is to measure the resistance of the test piece offer to bending, in the region of elastic deformation.
- The tester is suitable for corrugated paper board (Flute A, B, C, D & E).
- A precise sensor measure the linear deflection caused by bending display on the screen and send to the micro-processor for calculation through the communication port.
- Automatic zero set point of the transducer compensate various thickness of the paper board.
- Length of paper board is adjustable from 50 to 300 mm. Make use of a stepping motor, left/right turn ball screw, the change of paper board length is much easier, the required
- length can be set and automatically done by the machine.
